Topic: UCX Instrument inputs question.
Hello everybody
I wanted to ask a question about my interface. Recently I have noticed that when I am playing music on my studio monitors and the instrument inputs 3 and 4 of the interface are in + 4dbu and instrument mode the levels are increased by 10 db. I did a test recording to see what that noise was and I was able to see that the interface itself over the air was taking the sound from the monitors (raising the signal 30db). Like this I did another test recording and shouting towards the interface and it took my voice in the recording (again it is heard raising it 30db). So far I only see what happens in inputs 3 and 4 when these conditions are given (+ 4dbu and instrument mode) On the other hand, it happens to a lesser extent if the inputs have something connected. But it still happens.
I wanted to know if this is a error, damage, or something common. The interface is old, I have it for at least 3 years, I bought it used and I have no contact with its former owner. Usually I never get into trouble when i record but it its strange and i wanted to ask.
From already thank you very much!
Greetings!
